Redux-SendActionDataToStore

// this is a common practice i think to make the object property values immutable
const ADD_NOTE = 'ADD_NOTE';

// only function of the reducer method is to change state based on an action.
const notesReducer = (state = 'Initial State', action) => {
  switch(action.type) {
    // change code below this line
    case ADD_NOTE:
    return state= action.text;
    // change code above this line
    default:
      return state;
  }
};

// action creator which returns an object with at least a TYPE property and in this case also a note property
const addNoteText = (note) => {
  // change code below this line
  return {type: ADD_NOTE, text:note}
  // change code above this line
};

// const in order to create the redux store for the application.
const store = Redux.createStore(notesReducer);

console.log(store.getState());
store.dispatch(addNoteText('Hello!'));
console.log(store.getState());
